Original Kurzfassung:
We present an algorithm that allows for indexing music by
topic. The application scenario is an information retrieval
system into which any song with known lyrics can be inserted
and indexed so as to make a music collection browseable
by topic. We use text mining techniques for creating a
vector space model of our lyrics collection and non-negative
matrix factorization (NMF) to identify topic clusters which
are then labeled manually. We include a discussion of the
decisions regarding the parametrization of the applied methods.
The suitability of our approach is assessed by measuring
the agreement of test subjects who provide the labels for
the topic clusters.
